## What it is
A tutorial repository demonstrating techniques to minimize Rust binary size, covering Cargo profiles, symbol stripping, LTO, UPX compression, and no_std/wasm builds. It serves as a reference guide with example configurations rather than a reusable library.

## Use cases
- reduce rust binary size
- shrink rust executable for containers
- optimize cargo release profile for size
- strip symbols from rust binary
- compress rust binary with upx
- build minimal rust wasm binary

## When to choose
- you want proven, up-to-date Cargo.toml settings for small Rust binaries
- you're targeting embedded, wasm, or container images where binary size matters
- you need a quick reference for strip, LTO, and opt-level options

## When to avoid
- you need a library or tool that automates size optimization rather than documentation
- your project prioritizes runtime speed or debuggability over size
- you need guidance for languages other than Rust

## Facets
- artifact type: learning-resource
- maturity: active
- function: build-tool, compiler, developer-tools
- domain: developer-tools, performance, programming-languages
- platform: rust, windows, wasm
